Will Haven concierge be able to help on fully booked excursions?

I just called NCL and he confirmed the tour was indeed sold out and wait listing was not available until trip starts.

So my best bet would be the concierge the very first day, I hope bluesea777 is right that 2/3 seats will be available on board...

As is ture with almost all AK excursions they sell out early, and when the seats are gone they are gone. None are held back, and no one will be able to get you on the excursion if it is full. It is very late in the season to be looking for excursions, but you might find something similar by doing it independently.

I agree, call NCL excursion desk and ask. There could be other reasons it has disappeared off the website. As for the Concierge helping, it is worth an ask but they can not put extra seats on buses just because they want to, so they may not be able to do anything.

 

Hope you get it worked out, sounds like a wonderful excursion

True, but if there are enough people to warrant another bus, I have seen that too. A boat, not so much. You can also try to book something on your own.
